ANDREW O. HURLEY, OF J EANNETTE, PENNSYLVANIA.

GLASS-HEATING OVEN.

SPECIFICATION forming part of Letters Patent No. 526,528 dated September25, 1894.

Application filed November 3, 1893.

To aZZ whom it may concern.-

Beit known that I, ANDREW 0. HURLEY, of J eannette,in the county ofWestmoreland and State of Pennsylvania, haveinvented a new and usefulImprovement in Glass-Heating Ovens, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification, in which- Figure 1 is ageneral plan view of a flattening oven provided with my improved heatingoven. Fig. 2 is an enlarged plan view of the heating oven alone. Fig. 3is a front elevation of the same. Fig. 4 is a horizontal sectlonal viewof the oven above the carriers. Fig. 5 is a vertical longitudinalsectional view on the line V-V of Fig. 4.. Figs. 6 and 7 are side andtop plan views respectively of one of the carriages; and Figs. 8 and 9are cross-sectional views of the guides upon the carriage. Figs. lOand11 are side and top plan views of one of the saddles; and Figs. 12 and13 are opposite end views of the same.

Like symbols of reference indicate like parts in each.

My invention relates to the improved glassheating oven disclosed in myprior patent, No. 478,328, granted July 5, 1892, and is designed toprovide improved means for carrying the glass cylinders through theheating oven to the flattening wheel.

To that end it consists in an endless carrier having removable saddlesarranged to support the glass cylinders and means for mov ing thesaddles laterally from the chain into the flattening oven.

It also consists in the construction and arrangement of parts ashereinafter more fully described and set forth in the claims.

In the drawings, 2 represents the flattening oven and 3 the preliminaryheating oven arranged to gradually heat the cylinders on their way tothe flattening stones. To move the cylinders step by step through thisheating oven, I provide an endless carrier consisting of two parallelsprocket chains 4 and 5,

wardly projecting lugs 9. The rests consist Serial No. 489,938- (Nomodel.)

' tracks, and to them are secured the projecting pointed lugs or guides17 and 18, the pair 17 being at a higher level and spaced farther apartthan the pair 18. To the front bar let is secured the forwardlyprojecting plate 19, having a hole 20 for the insertion of the hookedinner end of arod 21 movable through a hole in the wall of the heatingfurnace in line with the flattening oven and arranged to push the saddlefrom the rest upon a track 22, which is in alignment with the track 8upon the rest in its innermost upright position. The track 22 extends tothe flattening wheel, as shown in dotted lines in Fig. 1.

The heating-oven is provided with suitable mantels 23, roof doors 24,and avertically adjustable front door 25, operated by a suitable chain26. The endless carrier is actuated by external sprocket gearing 27connecting with the shaft carrying the inner sprocket-wheels 7, thisgearing being actuated by crank 28.

The operation is as follows: The carrier being moved intermittently bythe handle 28 a distance equal to the spacebetween the rests, and theglass cylinders placed upon each saddle in its outer upright position,at each stop the track of oneof the rests is inline with the track 22.The rod 21 then being engaged with the plate 19, the saddle is pushedfrom the rest into the flattening oven upon the track 22, the lugs 17and 18 leaving the holders 10 and 11. The flattener removes the cylinderfrom the saddle, which is then pulled back into place upon the rest andheld thereon by the lugs entering the holders. The carrier then. beingadvanced another step, the action is continued.

The advantages of my device result from its simplicity and cheapness,the perfect control had over the movements, and the few I I andrelative"zirna ngeinent ef Off apparatus may he" made" by thnseskilledina the art within theseope of my invention; as-
